1995 50 hrs merc. oil injected. I put my boat in this spring and did not know it had somehow collected water in the oil reservoir. As a result, I have lost compression in the top cylinder of 3. Without complete disassembly is there any way to regain compression. There is no head but I do not believe the cylinder is scored. I think it could be the rings sticking. I took it to a marina and they wanted to put a new power head on --$2,900, therefore i decided to try a few things out myself. I'll take any advice. p.s. I have no idea how water (1/2 a cup+-) got in there except maybe leaking around the fill gasket. In my opinion it is a poor design. Filler cap is outside the engine cover.
